Know therefore that Yahuha(YHWH) thy god, is The elhohim ; the faithful god, who keepeth covenant and mercy with them that love Him and keep His commandments to a thousand generations;
The pronouncement of יהוה as Yahvew is likely wrong compared to Yahuha.
Most ancient tablet, scrolls be it the silver scrolls or dead sea scrolls shows that Hebrew & pleo-Hebrew is based on vowels
like English and many other languages. יהודה is pronounced as Ya(י)-hu(הו)-da(דה). Why would the first 3 letters be pronounced differently unless the niqqud changes them. Another example can be found in the names Natan-Yahu and Yahu-Natan which means Yahu has given.
The Niqqud system would also be hard to notice or bothersome when carving on stones.
On paper its a waste of ink. In other words the Niqqud existence make no sense, they have no use unless its to deceive or complicate.
The Niqqud or Dagesh system is a later addition, some claim that its being used to obscure the more right way to pronounce his name. It could be even against Yahuha's will since he proclaim all the world would know his glory. If I recall correctly, its good or his will that people would know and call his name.
The Kabbala, which has roots in other nation such as India & Hinduism whose practice is forbidden according the law given from Yahuha to Masha(Moses), is example of rebellion, corruptions due infiltration, ignorance or a mixture.
There is also Deuteronomy 4:2
You must not add to or subtract from what I command you, so that you may keep the commandments of Yahua your god that I am giving you.
which pertains to additions such as the Kabbala, the Talmud(The term Talmud normally refers to the collection of writings named specifically the Babylonian Talmud) and so can tradition.
